New Injector Seals = Long crank??

I just replaced the injector seals on my 7.3L 01 F350 395k miles. It was beginning to give the signs of long crank and only hitting on a couple of cylinders and having to hit it with a little starting fluid to get it to fire up. However, if plugged in it would fire right up and be ready to go in a few seconds. 3 to 5 seconds worth of crank would light it up. If the truck was warm it would always fire on about 5 sec or less starting. Now I just replaced the injector seals and now if the truck sets for 30 seconds or more it takes a good 10 or 15 seconds to fire. Does it take a while for the HP oil system to purge out the air? Did I mess something up? Any suggestions will help.

Well if it was the injector seals that were the initial problem, you would have solved it. My guess is its not the injector seals entirely. I'm sure they were bad, but lets not forget how an injector wears out. What you have is worn injectors making it difficult to start.

Why didnt you replace the injectors when you had it apart?

The only time I was having the starting issue was when the engine had sat for over 8 hours in the cold. This long crank issue only began after the dis-assembly and reassembly. Not just after setting for a few seconds and then a warm restart. After driving it today the crank time is now down to about 5 or 6 seconds. It seem to be getting better as Steve stated.

I had the injectors tested by the dealership and they stated that the injectors seemed to be fine and that I should only have to replace the seals. Don't know the method that they came to that conclusion but if they thought new injectors were in order they would have tried to sell them to me.

Thank you guys it seems to be getting better and even starting it cold this morning other than the long crank it seem run fine after it fires up.

It was 31 degrees f this morning and it started without being plugged in. It has been a while since it did that. Before if it was below 50 it would not hit.

Thank you all for your support.
